Set up MAC address filtering
MAC filtering allows you to define up to twenty Media Access Control (MAC) address filters to
prevent computers from sending outgoing TCP/UDP traffic to the WAN via their MAC
addresses. This is useful because the MAC address of a specific NIC card never changes, unlike
its IP address, which can be assigned via the DHCP server or hard-coded to various addresses
over time.
To configure MAC Address filters:
1.
From any SBG10 Web Manager screen, click the
Wireless 2.4 GHz
or
Wireless 5 GHz
main
menu button
on the
SBG10 Web Manager menu bar.
2.
Click
MAC ADDRESS CONTROL
from the
Wireless
submenu options list to display the MAC
Address Control screen.
